NO. 17 Lamarck's genera of shells — kennard et al. 37 



Genus Type & .Synonym 



A. argo 



§Lk. Prod. 79 cited A. argo, Lin., but in Syst. 99 

 changed the name to A. sulcata, reverting, 

 however, in the Hist, to argo. Mft. ii, 7 

 adopted the synonymic A. sulcata. By typo- 

 graphical error the generic name appears 

 under his figure in some copies as "Aargau- 

 nota." 

 253 166 Octopus [No shell.] 



§[Type Octopus vulgaris, Lmk.] 



253 t66 Loligopsis [No shell.] 



§ [Lamarck's generic name for sole species L. 

 pcronii dates from 1822 and is anticipated by 

 Lcachia, of LeSueur, 182 1.] 



254 167 LoUgo L. vulgaris (Sepia loligo. hum.) 



[Genus originally founded by Schneider, 1784, 

 who mentions in the text L. niaxiuia, but type 

 is obviously the Sepia loligo, Lin. Lamarck in 

 1798 employed the same generic name and 

 amongst his species is L. vulgaris, a synonym 

 for Sepia loligo, Lin. 

 254 167 Sepia 



256 169 5". officinalis (Idem. Linn.) 



§Same in Lk. Syst. 59. 



257 170 Cariiiaria C. vitrca (Patella cristata. Linn.) 



§Genotype, Lk. Syst. 99, is C. vitrea, n.n. for 

 Patella cristata, hin. = Argonauta vitreus, 

 Gmel. The correct type name is, therefore, 

 Carinaria cristata (Lin.). 



258 171 Pterotrachca [No shell.] 



§[Lk. Syst. 61 cites P. coronata, Forsk.] 

 258 171 Phylliroe [No shell.] 



§[Sole species cited by Lamarck is P. bucepha- 

 lum, Peron. Genus founded in 1810 by Peron 

 and LeSueur, but species cited by them in 

 vernacular.]
